Application filed November 10,y 1913. lSerial No. 800,181. l

To all whom it may concern Be it known that I, FRANKLIN l?. WHITE.,

a citizen of the United States, Iresiding at Shallotte, in the county `of Brunswick and State' of North Carolina, -have invented a' spokes to be removed and replaced or re-l paired without removing the tire or'rim 0f the wheel.

l responding parts in all the figures of the ,'With these and other objects in view the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying,v drawing and pointed out in the claims hereto appended, it 4being understood that various changes inthe form, proportion and minori details of construction within Athe scope of the claims may be resorted to without'departing from the spirit or sacrificing any of the advantages of the invention. n.

Fig. 2 is an enlarged sectional view taken longitudinally of the hub. Fig. 3 is a similar view taken transversely of the hub. Fig. 4is a detail longitudinal sectional view of the mainsection of the hub. Fig. 5 is an enlarged detail section View illustrating the manner of interlocking the axle box with the hub.l Fig. 6 Lis a perspective detail view rofone of the wedges. Fig. 7 is a detail view of a portion of the axle `box showing the. exterior ratchetv recesses for engaging the wedges. y p

Like numerals of reference designate cordrawing. n

ln the accompanying drawing in which is illustrated the preferred embodiment ofthe invention, the metallic hub, which may'l be constructedof any suitable metal, comprises in its construction a main section l having a xed annular `flange 2 and amovable sectionS` carryingan adjustable annular flange., 4 spaced from the lixed annular kflange 2 to receivethe innerends of spokes 5.y The` spokes 5 lare clamped betweenv the annular.

flanges 2 and 4 and areheld against outward radial movementby kannular ribs 6 oppositely beveled `and adaptedto beem-y bedded in the,` side edges ofthe inner ends of the spokes, as clearly illustrated inFig. r2

of the drawing. i The annulari spoke clamping flangesQ and 4, arep'referably braced by webs 7 and 8 formed integralwith the main andremovable sections of l.the hub.

The main section consists of a substantially cylindrical body reducedat the outer porj g i tion 9y tojreceive the removable section 3` whichisiretained on the Umain section in engagement vwith the `spokes by means `of a cap nut 10 yarranged yon ythe outerL end 11' of the ymain section: 'lk `which `is exteriorly threaded toengage'the interior threads of thek cap v nut.,y The cap ynut falso formsk a closure for the outerend of thehub and excludes dustanddirt from the interior against -the exterior ofthe central portion ofthe main section.,r of 'the hub, and the shoulder 12 yformedlbyy reducing the outer portionof the` main section is; spaced! from ythereof.l The inner ends ofthe y"spokes fit j the. clamping'fflange 4 to enablethellatter to be drawn tightly into engagement with the `.spokesby a series of bolts 13 piercing the flanges 2 and 4 and passing betweenthe adjacent spokes, which "arefprovided with registering grooves 14 `for theebolts, as

,clearly illustrated in Fig. v3 kofthe drawing.

Theouter ends of the spokes are secured in the usual manner to4 a'rim orfelly lhaving a tire 16' arranged on'it.y yWhen it is desired to remove a spoke or otherwise revpairthe wheel the section 3 may bey detached by -v,removing `the e axle nut to .expose the spokes'and lpermit the latterto be removed without taking off the rimf or tire of kthe wheel..- o .i

No claim, is ymade in the present application to the means for clamping the spokes. The hub, which is interiorly rrecessed at the inner end to provide axprojectingcufi` v or'portion la to fit/over the collar` lfat the inner end ofthe spindle l18 of an axle 19,

`has its interior oppositelyy tapered linwardly from eachend, asclearly shown in Figs-12 and 4 of the drawing; but in short hubsonly a single taper may be provided. The tapered portions 19a' and 2O of the interior of the hub are provided with recesses or cavities 21 preferably forming an annular series ties of each row being staggered'with relation to the recesses or cavitiesofthe adjacent rows. Each recess or cavity tapers longitudinally and also in depth and is curved transversely, forming a shoulder 22 at one end, the shoulders 22 of each row being arranged opposite the intervals or spaces between the shoulders of the adjacent rows. The shoulders of the recesses or depressions form ratchet teeth and are adapted to engage wedges 23 and arranged in inner and outer series and preferably constructed of wood and adapted toenable an axle box 24 to be centered or trued with respect'to the rim whenit becomes necessary to true the wheel. This construction provides a metallic hub capable of having its axle box trued from time to time with the rim, thereby greatly increasing the life of a wheel. j

The axle box which has asmooth interior to form a bearing for the spindle is exteriorly tapered and is provided with exterior cavities or recesses 25 arranged in longitudinal rows and staggered similar to the recesses or cavities of the hub. The recesses or cavities of the axle box correspond in size, shape and construction with the recesses or cavities of the hub and they form end shoulders 26 for engaging the wedges 23. The wedges23 which are driven into the hub betweenthe inner face thereof and the exterior of the axle box are tapered longitudinally and have their side faces curved transversely presenting convex surfaces to' the hub and the axle box. One-side face 27 of each wedge is preferably recessed to form a longitudinal series of tapered portions 28 having end shoulders 29 toengage` with the recesses or cavities of either the hub or the axle box; but each face of the wedges may be similarly recessed if desired. rIhe wooden wedges which ena-ble the axle box to be readily driven out of the hub when desired, constituting a simple and eiicient means for securing the axle box within the hub and they enable the axle box to be readily trued and they hold the axle box against sliding movement longitudinally of the hub and also prevent any radial or rotary movement axle box. of longitudinal rows, the recesses or caviof the vspindle `is reduced and threaded to receive an axle nut 32 arranged within the cap nut 10 and engaging the outer end of the The spindle is preferably provided with longitudinal and annular lubrication -receiving and distributing grooves 33 and 34,- and lubricationis supplied to the bearing of the wheel by inner and outer cups 35, havingV suitable closures 36 and provided with threaded stems 37 mounted in threaded openings 38 in the main section of the hub and having tapered terminals 39 which fit in tapered counter-sunk openings 40 in the axle box. The ad'ustable section 3 of the hub is provided wit a slot 41 to receive the stem of the outer lubrication cup so that the latter will not interfere with any adjustment of said section 3. The section 3 is also provided with a slot 42 having a set or clamping screw 43 mounted in athreaded opening 44of the main section of the hub and engagingA the exterior of the axle box.

Any number of sets of wedges within the capacity of the hub may be employed for securing the axle box in place, and the main section of the hub is preferably provided with a central longitudinal rib 45 which forms a stop for the inner ends of the adjacent spokes.

lVhat is claimed is:

1. A'metallic hub including a metallic axle box, and a-plurality of Wedges consisting of independently adjustable bars of relatively soft material arranged4 within the hub and engaging the axle box and holding the latter in position. Y j' j 2. A hub provided with interior shoulders or teeth and including an axle box, and a plurality of wedges consisting of independently adjustable bars interposed between the axle box and the hub and engaged by the said shoulders or teeth of the latter.

3. A hub including an axle box provided with exterior shoulders or teeth, and a plurality of wedges consisting of independently adjustable` bars arranged within the hub and engaging the shoulders or teeth of the axle box. Y

4. A hub provided with interior shoulders or teeth and including an axle box having exterior shoulders or teeth, and wedges consisting of bars of relatively soft material arranged within the 'hub and interposed between the same and the axle box and engaging the said shoulders or teeth. .l

5. A hub having an axle box and provided with interior recesses or depressions arranged in rows f and tapered longitudi-V nally, and wedges arranged within the hub around the axle box and engaging the said recesses or depressions. y

6. A hub having an axlel box and provided with interior recesses or depressions arranged inrows and tapered longitudinally, and wedges arranged within the hub 4hub and interpose around the axle box and tapered at intervals to provide projecting portions for engaging the recesses or depressions.

7 A hub having interior recesses or cavities arranged in rows and tapered longitudi? nally, an axle box arranged within the hub and provided with exterior recesses or, cavities also arranged in rows and tapered longitudinally, and wedges arranged within the hubl around the axle box and engaging the said recesses or cavities. y

8. A hub having interior recesses or cavities arranged in rows and tapered longitudinally, an axle box arranged within the hub and provided with exterior recesses or cavities also arranged in rows and tapered longitudinally, 'wedges arranged within the between the interior thereof and the axle box and provided with tapered portions for engaging with the said recesses or cavities. i

9. A hub having its interior tapered inwardly from each end, an axle box arranged within the hub, and innerand outer series pered longitudinally and curved in `cross f' section and forming shoulders, and wedges arranged withinthe hub around lthe axle box and presenting curvedv side faces and consisting of a plurality oftapered portions for engaging the recesses or cavities.

In testimony that Iuclaim the foregoing as my own, I have heretor aiixed my slgnature in the presence of two witnesses.
